Purposive sampling is a widely used non-probability technique that is integral to qualitative and mixed methods research for its focus on detailed and contextual understanding. Purposive sampling which is defined as the intentional selection of specific units (such as individuals, cases, or events) based on their relevance to the research question, enables the researchers to gain deep insights into complex phenomena. While purposive sampling offers advantages like cost-efficiency, flexibility, and the ability to target information-rich cases, it is often criticized for its lack of generalizability and susceptibility to researcher bias. This paper explores the concept of purposive sampling, its theoretical framework, and its practical applications in research. Additionally, it examines its strengths and limitations which are supported by case studies from education and social sciences. By presenting a nuanced discussion, the article aims to guide researchers in effectively employing purposive sampling to achieve rich, context-specific data while addressing inherent methodological challenges.
